Advent Technologies Membrane Electrode Assemblies (MEA) for High Temperatures PEM fuel cells

Advent Technologies High Temperature (150-200oC) MEA is based on pyridine type proprietary ADVENT TPS® polymer electrolytes. ADVENT TPS® technology is polybenzimidazole (PBI) free and less expensive than the competition, allows the use of fuels with high CO content and reduces the complexity and the cost of the final PEM fuel cell system

Advent TPS® MEA Characteristics

• Operational temperature 150-200^oC
• Pyridine based aromatic polyether electrolyte
• High Carbon monoxide tolerance
• Long term stability with small voltage drop
• Zero degradation under cycling operating conditions
• Endurance under differential pressure
• No need for humidified gases
• Easier to mass produce due to favourable membrane properties
• Low cost
